Application October 6,

2 Claims.

This invention relates to window frame constructions and, more particularly, to .a window frame construction in which sash weights or cords are not used and in which the window sashes are .5; easily removable from the frame structure without removing portions of the frame.

In the usual window frame construction, when it is desired to remove the window sashes from the frame, part of the jamlomust be removed by pulling nails or removing screws therefrom and then removing the sash cords from the window sashes. In such window frame constructions when it is desired to wash the outside surface of the window glass or paint the outside surface of the frame it is necessary for the person doing the same to either lean outside the window or to approach the window from the outside which is usually'inconvenient and dangerous.

In the applicants construction, the window sashes are easily removable from the remainder of the frame without the necessity of removing nails or screws from positions of the frame. No sash cords or weights are used and the windows are easily removable by merely sliding them from the frame.

When it is desired to wash the outside surface of the window glass, the windows may be swung inwardly, independently of one another.

One object of my invention is to provide a window frame construction whereby boththe upper and lower sashes of a window frameconstruction may be removed from the window frame independently of another without taking the frame apart.

Another object of my invention is to provide a window frame construction in which sash weights and cords are not used.

A further object of my invention is to provide a window frame construction whereby the upper and lower sections of a window may be swung inwardly and the outside surface of a window glass cleaned or the outside of the sash painted from the inside of the building. g

A still further object of my invention is to provide a window frame construction in which the movable sections are sealed in order that drafts may be prevented.

Other objects will appear or will be obvious from a consideration of the detailed description which follows when taken in conjunction. with the accompanying drawings.

, The device of the present invention consists of a window frame construction having jambs on either side of the window opening, the. jamb on one side of said window opening consisting of two 1938, Serial No. 233,572

adjacent longitudinal channel portions having a common side the lower section of the channel portion on the outward side of said jambbeinghingedly mounted to swing inwardly. the other side of the lower portion of the innermost channel being hingedly mounted and adapted to swing inwardly, the jamb on the opposite side of said window opening consisting of two adjacent longitudinal channel portions having a common side and opposite the channel portions in the firstmentioned jamb, the channel portion on theinner side of said window frame being hingedly mounted and adapted to swing inwardly, the common side of said channels swinging inwardly there? with, an upper window sash slidably mounted in p the channels in said jambs on the outer side of said window frame, a lower window sash slidably mounted in the channels on the inner side of said jambs, rollers mounted on the sides of said windowsashes to cooperate with said channels, a plurality of apertures in the bottom of said channels, and a spring tensioned pin mounted on the side of said window sashes and adapted to normally engage said apertures.

It will be understood, however, that the invention is not restricted to the exact disclosures but is susceptible to such ohangesand modifications which are within the scope or purview of the appended claims.

Referring to the accompanying drawings Figure 1 is an elevational View of the window frame construction of my invention, part of the jamb being broken away. I

Like numerals refer 'tolike parts throughout .the several views.

The window frame construction of the present a1 section on the line 33 invention consists of the usual trim having portions it and H along the side of the window opening, the portion l2 along the top: of the same,

and window sill l3 across the bottom of the window opening. J ambs i4 and i5 extend longitudinally from the top to bottom of said opening.

The jamb l5 consists of two longitudinal channels i6 and i1 extending from the top to the bottom of the window opening. The channel It being formed by an outer side piece 2!, a bottom 22 and a side piece i8. The channel H is formed by the side piece 3 which is common to both channels it and IV, the bottom 23 and side piece,

26. The side piece 25 is separate from the bottom piece 23 from the window sill I3 to a point 25 adjacent the top of the window opening and is hingedly mounted at 26 and 2? to the trim Ii so that it may swing inwardly. The bottom piece' or may be formed as shown in the drawings of a separate side piece 2! attached to the bottom 22 and side piece l8. This lower portion of the channel I6 is hinged at 28 to the bottom 23 of the channel ll, so that the bottom portion of said channel i6 may be swung inwardly.

The jamb 14 on the opposite side of the window opening consists of two channels 29 and 312, the channel 29 being laterally opposite the channel it and the channel 30 laterally opposite the channel ll,

The channel 29 is formed of side piece 3!, a bottom 32, and a side piece 33. The channel all is formed by the side piece '33, which is common to both channels 29 and 36, the bottom piece 34 and the side piece 35.

The bottom portion of the channel 30, which is the same length as the window sash to be mounted therein, consists of the side piece 33 which is fastened to the bottom 34 and the side piece 35 which is alsofastened to the bottom 36. The bottom section of the channel portion 38 is hingedly mounted to the trim in at 3B and 39, so that the same may swing inwardly. The side portion 35 may extend to a greater distance toward the top than the length of the window sash, for instance, to a point as shown at dd in Figure 1 in the drawings.

The bottom portion of the channel 25 is stationary as is the top portion of the channels 29 and 38. I

, A Window sash M having a pane of glass 42 and forming a closure for the top section of the window opening is slidably mounted in the laterally opposite channels [6 and 29. Rollers 43 are mounted, preferably one at the bottom and another at the top of both sides of thewindow sash ll so that they cooperate with the channels l6 and 23in order that the window sash may be opened and lowered with ease.

Spring tensioned pins 44 are mounted on the sides ofthe window sash 4H and are adapted to cooperate with a plurality of apertures 35 in the bottoms 22 and 32 of the channels l6. and 29 respectively. The pins 34 engaging the apertures 45 hold the window section M at a desired position when the same is raised or lowered. The apertures may be drilled in the bottom'of the channels l6 and 29 or may be drilled in a sepanel. dow sash 4! are of similar construction.

rate plate and the plate fastened on the bottoms of the respective channels.-

Slidably mounted in the laterally opposite channels H and 38 is a lower window sash 46 having a pane of glass t'i mounted therein which acts as a closure for the bottom section of the window opening.

Mounted on both sides of said windowsash 46 are rollers 48 adapted to cooperate with channels H and 3G in order that the window sash it maybe raised and lowered with ease. v

The rollers 48 may be mounted in a bracket 49, as shown in Figure 4, and countersunk in the side of the window sash it, the circumference of the rollerbearing against the bottom of the chan- The rollers 53 mounted on the upper win- A spring tensioned-pin Elli is mounted at the bottom of both sides of the window sash 46 and cooperates with a plate 5! having a plurality of apertures 52, as shown in Figure 4, mounted on the bottom of the channels H and 38 as shown. The pin 5%) is mounted'in a bracket 53 which, in turn, is mounted in the sash, as stated above, and has a shoulder- 54 fastened thereto which'is adapted to press against a spring 55. When any pressureis exerted against the window sash to raise or lower the same, the pin5i3 is released from an aperture 52 by said pressure against the tension of the spring 55 allowing the window to be raised or lowered. When the window is raised or lowered to the desired position, the tension of the spring 55 presses the pin 50 into an aperture 52,'the tension of the spring being such asto hold the pin in the aperture against the weight of the window sash. 1 f

The operation of the'pins 44 on the upper win-'- dow sash 1! is similar to theoperation of the pins 50. I

'I hewindow sash 46 when in its lowermost position rests upon pins 5% and 5'1 which coo-perate with apertures in the bottom 01" the window sash. u

A triangular shaped weather strip 58 is fas.-. tened to theouter side of the top piece of the window sash 46 the hypotenuse of the same engaging thehypotenuse of a similar triangular strip fiii fastened to the inside of the bottom piece of window sash I ii. As Weather strip 60 is fastened to the bottom of the sash 46 to effectively seal the sash against the window sillv i3 whenv the window is closed.

A handle 61 is fastened to the lower window sash d6.

The window opening has the usual trim 62 around the outer side thereof.

vIn operating the windows of the present device, when it'is desired to open the bottom section of the window comprising the sash 46- in which the pane til is mounted, upward pressure is applied to the handle 6|. are bevelled on the endwhich engages the apertures 52- and are in their normal position in engagement with said apertures, which are also bevelled to conform to the end of the pins 59, are disengaged from the aperturesagainst ;the tension of the spring 53, permitting the window sash Etto be raised, the channels I? and 3t guiding the same and the rollers d'bearing against the bottoms 23 and; 340i the channels allowing ease in such raising. When thewindow is raised to the desired height, the pin 50 engages one of theapertures 52 through the tension of the spring sa'thetension or said spring such as to hold the 7 5 I The pins 50, which pin in the aperture under the normal weight of the window sash.

When it is desired to close the lower window section, downward pressure is exerted on the window sash 46 which disengages the pins 58 from the apertures 52, the action of the pin being the same as when the window is opened.

If it is desired to lower the upper window section comprising the upper sash ll, a downward pressure is exerted on the same, the pins 44, which are similar in construction to the pins 55 mounted onthe lower window sash it are disengaged from the apertures 55, which are similar to the apertures 5?. in the channel 343, permitting the upper window sash t to be lowered. The window sash M is guided by the laterally opposite channels l6 and 29 the rollers 53 permitting the sash to slide freely in said channels.

When the upper window sash ll is lowered to the desired level, the downward pressure is released and the pins fidthrough engagement with the apertures 45 hold the sash in this position, the spring tension on the pins it, like the spring tension on the pins 53' on the lower window sash, being sufiicient to hold the window sash in such a position under the normal weight of the sash.

If it is desired to raise the upper window sash 4! an upward pressure is exerted on the window sash which disengages the pins i l from the apertures t5 permitting the window to be raised to the desired height, the pins then engaging the aperture and holding the window in this position.

With this construction no window sash weights or cords are required and a construction permitting ease in lowering and closing windows is provided.

Should it be desired to swing the window sash 4B inwardly the window sash is placed in its fully closed position. A look 63 having a pin fi l cooperating with an aperture 65 in the sill i3 is operated to disengage the pin t l from the aperture 65 permitting the side piece 2 3 to be swung inwardly on the hinges 2t and 2?. When the side 24 of the channel ii in which the sash 46 slides is in this manner removed, the window may then be swung inwardly, the lower portion of the laterally opposite channel 35, in which the window sash 46 is slidab-ly mounted, swinging inwardly on the hinges 33 and 39 as shown in Figure 6 of. the drawings. In this manner the outside surface of the pane of glass ll may be cleaned from the inside of a room without danger or inconvenience to the person cleaning the same or the outside surface of the window sash may be easily painted from inside of a room.

The window may be fully removed from the channel 33, as shown in Figure 5 of the drawings, by raising the same so that the pins 56 and 51 are disengaged from holes in the bottom of the window sash 66. The window sash may then be easily removed from the channel by moving the same away from the channel as shown in Figure 5. v

When it is desired to swing the upper window sash 4| inwardly, a downward pressure is exerted on this section and the window sash lowered until the bottom of said sash engages the window sill. Since the common side 33 of the channels 29 and 30 has been disengaged from the channel 253 when the lower sash 45 was swung inwardly, the upper sash may be swung inwardly away from the channel 29. The bottom portion of the channel it, which is laterally opposite the channel 29, is then swung inwardly on the hinges 28 which are mounted on the bottom 23 channel 'il as shown in Figure '7.

A hook 86 mounted on the top of the window sash l! engages an eye ti mounted on the side piece 21 of the channel when the sash is lowered and prevents the. top portion of the window sash from coming disengaged from the channel.

A pin 68 mounted on an extension at the bottom of the side piece it of the channel 6 engages a hole in the bottom of the window sash iii when the same is lowered which will prevent the bottom or this window sash from becoming disengaged from the channel.

When it is desired to remove the window sash ii from the Window opening, it is merely necessary to lift the sash until the hook 6! no longer engages 3! and the pin 68 is disengaged from the hole on the bottom of the window sash. The window sash may then be removed from the channel it.

The present construction, therefore, permits the removing of both the window sashes independently of one another without removing any of the window frame or trim and without the necessity of removing any sash weights and cords from the window sashes.

It is, of course, understood that the construction of my present invention is capable of being varied in difierent ways to accomplish the purposes set forth, and it is not my intention to limit the invention to the exact details of construction shown and described, but rather to cover all equivalent structures as-defined by the scope of the appending claims.
